Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is designed to compare analgesic effect of both the ultrasound (US)-guided QLB and ESPB blocks during ESWL and their effect on stone fragmentation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Urinary tract calculi, one of the most common benign urological diseases, is seen in 12% of patients and has a recurrence rate of approximately 50%.

Management of renal calculi is known to be affected by many factors, specially tolerance of pain during ESWL and how it is controlled.

Pain experienced during ESWL is thought to occur when shock waves from the lithotripter reach superficial structures such as skin and also deeper structures such as the ribs, nerves and the kidney capsule. There are three main factors that contribute to the propagation of pain at these structures: shock wave (SW) pressure, distribution, and focal area size .

Conventionally, pain during ESWL is managed by basic analgesics such as NSAIDs, which can also aid in stone clearance. Other methods of analgesia also have been studied and tested.

Quadratus lumborum block (QLB) was first described by Blanco in 2007, it blocks T7-L1 nerve fibres in most of the cases. Studies have reported its use in the management of postoperative pain after hip surgeries.

"Erector Spinae Plane Block" (ESPB) is another such block, that is increasingly tried for the management of postoperative pain for breast surgery, thoracic surgery, and also upper abdominal surgeries. ESPB when given at the lumbar region gives blockade from C7-T2 to L2-L3.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group Q

(n=30) will receive unilateral quadratus lumborum block type III

Group Type ACTIVE_COMPARATOR

Quadratus lumborum block type III

Intervention Type PROCEDURE

Patients will be placed in lateral decubitus position with the side of the target stone facing up. After sterilization and draping of the skin, using US probe the block will be applied targeting the fascial plane between the quadratus lumborum and psoas major muscles (anterior aspect of the quadratus lumborum). After 20 min, sensory blockade will be evaluated with pinprick test, if loss of sensation is achieved at the T7-L1 dermatome site, the block is considered successful and patients will be transferred to ESWL Room.

Group E

(n=30) will receive unilateral erector spinae plane block

Group Type ACTIVE_COMPARATOR

Erector spinae plane block

Intervention Type PROCEDURE

Patients will be placed in the lateral decubitus position according to the selected site. After sterilization and draping of the skin, using US probe, the block will be applied in the plane deep to the erector spinae muscles and superficial to the transverse process. After 20 min, sensory blockade will be assessed with pinprick test, if loss of sensation is achieved at the T7-L1 dermatome site, the block is considered successful and patients is transferred to ESWL Room.

Group C

(n=30) will be control group receiving no intervention, managed only with conventional analgesia
